Technical Abstract

A method for making a color separator configured for a large screen display includes covering red, green, and blue subpixels of a phosphor display with a refraction layer, and then ink-jet printing a color selection mask layer onto the refraction layer to shield the blue and green subpixels from a first beam, shield the red and green subpixels from a second beam, and shield the red and blue subpixels from a third beam.

Patent Claims
12 claims

Legal claims defining the scope of protection, as filed with the USPTO.

1

1. A method for making a color separator configured for an image display apparatus, comprising the acts of: providing a substrate; establishing phosphor-based red, green, and blue subpixels on the substrate; covering the subpixels with at least one refraction layer; and printing a color selection mask layer onto the refraction layer to shield the blue and green subpixels from a first beam, shield the red and green subpixels from a second beam, and shield the red and blue subpixels from a third beam.

2

2. The method of claim 1 , wherein the display is a large screen display.

3

3. The method of claim 1 , wherein the display is a phosphor display.

4

4. The method of claim 3 , wherein the phosphor display operates internally at atmospheric pressure.

5

5. The method of claim 1 , wherein the color selection mask is ink-jet printed onto the refraction layer.

6

6. The method of claim 1 , wherein the color selection mask defines plural excitation light apertures defining variable pitches established based on the locations of the respective excitation light apertures relative to the display.

7

7. The method of claim 1 , wherein the source is a laser.

8

8. A method for producing a demanded image, comprising: establishing a mask on a phosphor display, the mask having apertures defining pitches between adjacent apertures, at least one pitch being different from another pitch; receiving the demanded image; and directing light onto a display through the mask, wherein the mask is ink-jet printed onto the display.

9

9. The method of claim 8 , wherein the directing act is undertaken using plural light valves, the light valves being controlled in accordance with the demanded image.

10

10. The method of claim 8 , wherein the display is a phosphor display.

11

11. The method of claim 10 , comprising operating the phosphor display internally at atmospheric pressure.

12

12. The method of claim 8 , wherein the mask is configured to shield blue and green subpixels of the display from a first beam, shield red and green subpixels from a second beam, and shield red and blue subpixels from a third beam.
